cAsnMnNT-wrnnow SUPPORT Appncation mea 'July 22, n

This invention relates particularly to that type of window supportswherein the sash is carried by a plate which is in turn pivotallyconnected to a shoe having sliding engagement with a track mounted onthe window frame.

It is one object of the invention to provide a support of the characterindicated so constructed as to etfectually secure the sash against otherthan manual adjustment in any one of a plurality of angular positionsrelative to the plane of the ywindow opening.

It is another object of the invention to provide a support of thecharacter indicated that will permit the removal of the full width ofthe end of the sash toy which it is attached and function as a closurefor the opening so made.

In the drawing- Figure 1 is a plan view of the support.

Figure 2 is a plan view of the same partly extended, part being brokenaway.

Figure 3 is a sectional view on line 3-3 of Figure 1, showing also aportion of a sash.

Figures 4 to 9 inclusive are detail perspective views of otherembodiments of the invention, partly in section and parts broken away.

Referring now more particularly to the drawing, I show at 1 the baseportion of a track mountable upon the horizontal portion A of a windowframe in any suitable manner as by screws 2, the position of the windowsill being indicated at 3 and the stool at 4.

The track 1 includes an upstanding edge 5 facing the stool 4, the saidedge being turned inwardly into parallel relation to the base portion asshown at 6.

At 7 isshown a shoe slidably mounted on the track 1,-5-6, and includinga downwardly turned flange 8 engaging the base 1 and a downwardly turnedflange 9 engaging the outer surface of the upturned edge 5 on the saidtrack. Punched downwardly from the body of the shoe 7 are a pair of earsor fingers 10-10, these fingers reaching under and engaging the undersurface of the track edge 6 as clearly shown in Figure 3. e

At 11 I show a plate pivotally connected to the shoe 7 as at 12and'adapted to lie parallel with the base portion 1 of the track. This192e; 'serial no. 124,278.

plate 11 is secured to ythe ylower edge ofthe sash 13 by mean'sof'screwsinserted through holes 14 provided therefor, and has a flange 15, formedthereon to lie flush with the outer surface of the sash 13 and toclosely approach thebase 1 when the sash is'closed.

` Anarm 16 is pivot-ally connectedto the base 1 of the trackand alsotothe platexl'l- 'the arm 16 and the point 12 on shoe 7, the

shoe 7 movingalong the track 1-5-6 toward t-he arm r16 as shown` inFigure 2. `While thel frictional engagement between theseveral `parts ofthe shoe and track provide a certainamount'ofsiipport therefor, Iprovide a number ofi'spaced indentations in' the edge 6 of the track asindicated `at17 fto functiony as detents for the shoe. 7. Their1gers'-f`10'closely Vengage theedge 6 but are sufficiently resilientto slide over the detents 17 when extra force is appliedito the sashinopening or closing, the fingers 10 normallyy lying between the detents17 yand effectually held, against sliding vthereby except under abnormalpressure as above set forth.

While the above described means for holding the shoe 7 in a givenposition on the track y of, the fingers 10 being somewhat wider than thenotches and formed as shownto readily slide into and out of the notchesunder pressure.

In Figure "5 the shoe 7 carries a spring 19 on which is arranged a pin20and a thumbpiece21, a number of holes`22 being formed in track partein the path of travel of the pin. In this manner the shoe is efectuallysecured in position but easily released by removing the pin 20 from thehole 22 which it engages by pressure upon the part 21.

Figure 6 shows an arrangement where the spring 23 on shoe 7 simplycarries a button k24e engaging recesses 25 in track part 5, disengagingitself from the recess without the use oi a finger release.

In Figure 7 notches 26 are formed in the edge of the track portion 6 anda spring 27 carried by the shoe 7 has a bentI portion 28 formed thereinadapted to ride into and out of the notches 26.

Still a different form is shown in Figure 8 where parts as 29 arepunched out of the part 50i the track and bent inwardly intosubstantially parallel relation with the track part l, these parts 29being but4 slightly spaced apart as shown at 30. In this einbodinientthe ends of the fingers l0 on shoe 7 are bent downwardly and slightlycurved as shown so that when pressure is applied to the shoe 7 and it iscaused to slide along the track the finger ends 3l will slide along theedges of the parts 29 and drop into the spaces therebetween, e'ectuallyholding the shoe againstinovement except when extra pressure is appliedthereto to force the iingers out of the spaces 30.

In the embodiment of the invention shown in Figure 9 notches 32 areJformed in the edge of track portion 6. A spring 33 mounted on the shoe7 is bent as at 34 to positively engage and lock in notches 32, and isprovided with a nger release 35.

It is to be understood, of course, that while I have herein shown anddescribed certain specific embodiments of iny invention, changes inform, construction and method of operation may be made Within the scopeof the appended claim.

I claim c l c A Window support including a track hav'- ing a base havingone side thereof disposed at an angle and having the free edge of saidside extended inwardly and lying parallel to the base and havingupwardly struck indentations formed therein, a shoe having a ange on oneside thereof engaging the base between the sides of the latter andhaving a iange on its opposite side engaged over said angular side ofthe basel and the inwardly extended free edge thereof, a tongue struckinwardly from the top oi the shoe with its free end positioned under thefree edge of the base to engage the indentations therein',

a substantially L-shaped plate formed to be secured to a window sash andhaving one side pivoted to the top of the shoe and having its oppositeside extending over said flange of t-he shoe and engageable with thebase of the track, and an arm p-ivoted to the plate and to the track.
